Question

Either my brain is straight up goneskiis or I need assistance.

Answer 1

The answer is C. 89 in^2

This is found by (1/2($\pi r^{2}$))+70

r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5

You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.

Hope this helps!
